a corporation of New York Application September 9,1932, Serial Nacsazss Y 14 Claims.

This invention relates to locks. It is particularly directed to a device for locking a door, having a plurality of bolts operable by a single operation for locking or unlocking thesame.

An object of this invention is to provide in a lock of the character described, a casing attachablev to a door, and bolts projecting therefrom for engaging keepers on the floor and on the door jamb, the construction being'such that all of'the bolts may be readily projected by a turn of a knob or a turn of a key and without application of excessive force.

Another object of this invention is to provide a compact, strong and rugged lock of the character described, which shall comprise comparatively few and simple parts, which shall be inexpensive to manufacture, smooth and positive in operation and yet'practical and efficient to a high degree in use.

Certain features shown and described in this application are shown, described and claimed in our co-pending application Serial No. 606,499, filed April 20th,'1932.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will. be exemplified in the construction hereinafter described so and of which the scope of application will be indicated in the following claims.

Referring now in detail to the drawings, 10 designates a door adapted to be secured to the door.jamb 11 and the floor 12 by a lock 13, embodying. the invention. The lock 13 comprises a casing 14. fromwhichthere projects a bar bolt 16' adapted .to engage within a keeper 17 in the floor and which is provided with'a pivoted strut 5 bar or bolt.19 adapted to engage in keeper 20 in said floor. There further projects from the casing a horizontal bolt 21 adapted to engage within a keeper 22 mounted on the door jamb 11, and a U-shapd bolt 25 likewise adapted to 10 engagethe keeper 22; I

The casingl4icomprises a front wall 27,a top wall. 28, a bottom wall 29, anend wall remote from the edge of the door 10 and an end wall 31 adjacent to andpreferablyiflush with the 15 edgeof said door. The-rear of' the casing may be closed by a cover plate 32 resting on a ledge formed around the rear edge of the casing and screwed theretoby means; of screws 33.

' he inner surface of the front wall 2'7 is 20 formed with a pair of parallel guide Walls for slidably receiving; the horizontal bolt 21 which projects through an opening 34 in the front wall 3-1. Said horizontal bolt may be constructed substantially as shown and described in' our said co-pending application and comprises a portion 35 projecting toward the rear of the'casing and provided with a pair of spaced. symmetrically disposed pins 36, and 37. The bolt is further provided, forfthepurpose appearing hereinafter, with a pair of parallel, alignedrack portions 38 adjacent the upper and lower edgesthereof.

Slidablymo'unted on said bolt 21 for recipro:- catory movement in a direction transverse to the direction of movement of said bolt, is afmember 39 shown and described in detail in our said copending application and adapted to-bereciprocated either by the hand knob 40 mounted on the'front wallof the casing or by the key actuated mechanism 41 having an arm 42 engaging a portion 43- of said member. The top and bottom walls 28 and 29 of the casing are provided with aligned, parallel tubular openings 46 and 47, respectively, and slidably mounted in the tubular portion 46 is the U.-shaped bolt 25 made of two parts, 50 and 51 and likewise described in detail in our said co-pending application. The part ,50' isslidably mounted within said opening 46 and rotatably receives the cylindrical stem portion 52 of the part 51. Said stem portion 52 is provided with a pinion 53 adapted in one position of the bolt 25 to. coact with the teeth of the ratchet 38, for the purpose hereinafter appearing. The member 51 is further provided with: a square'shaped portion 530. alignedwith the stem 52, with a horizontal portion 54, and with an arm portion 55 parallel to the portion 53 and adapted to cooperate with the keeper 22.

For the purpose hereinafter stated, the rear cover plate 32 is provided with a pair of inwardly extending, symmetrically disposed and vertically aligned pins 57 and 58. Pivoted to the pin 57 is one end of a flat plate 59 substantially lying against the inner surface of said cover plate 32 and having a slot 60 receiving the pin 36 therethrough. Said plate 59 is formed with a small slot 63 adjacent the opposite end thereof, receiving a pin 64 fixed to the slidable por tion 50 of the U-shaped bolt 25. r

It will now be understood that as the knob 40 or the arm 42 is rotated, the member 39 will be reciprocated with respect to the horizontal bolt 21 and will cause reciprocation of said bolt; Movement of the bolt 21 will cause pivotal move- 7 ment of the plate 59 for causing reciprocation of the bolt 25. The plate 59 is preferably constructed and shaped substantially as shown and described in our co-pending application, and the slot 60 is so shaped that upon projecting the bolt 21 the U-shaped bolt 25 will move upwardly from the position shown in Fig. 4 until the square shaped portion 53a of the bolt part 51 moves out of the square shaped slot 46. Further projecting movement of the horizontal bolt will cause the bolt part 51 to be rotated from the position shown in Fig. 4 throughan angle of 180 by reason of engagement of the rack teeth 38 with the teeth of the pinion 53. Continued projecting movement of the horizontal bolt will cause the bolt 25 to be moved inwardly toward the horizontal mid-section of the casing so that the portion 55 thereof will engage the keeper 22.

Means is provided for projecting the bolt 16 simultaneously with the projecting movement of the horizontal bolt 21. To this end, said bolt 16 is provided with a bar portion 70 of substantially square cross-section, slidably extending through the tubular openings 47 in the lock casing 14. The inner end of said portion 70 may be provided with a pin 71.

A flat plate 72 lying substantially against the inner surface of the rear cover plate, is pivoted adjacent one end thereof to the pin 58 projecting from said cover plate. The opposite end of said plate 72 is formed with a small slot 73 slidably receiving said pin 71 therethrough. The plate 72 is likewise formed with a slot 74 receiving the pin 37 fixed to the portion 35 of the horizontal bolt 21. The slot 74 is formed with a portion 76 extending radially from the pivot pin 53 and in the retracted position of the horizontal bolt is substantially parallel to the horizontal mid-section of the casing 14. Extending from said portion 76 is another slot portion 77 inclined inwardly toward the horizontal mid-section of the casing; and extending from the other end of the slot portion 77 is a third slot portion 78 likewise extending radially with respect to the pin 58, and in the projected position of the horizontal bolt 21, said slot 78 is disposed substantially parallel to the horizontal mid-section of the eas- During movement of the horizontal bolt from retracted to projected position, the pin 37 will first move within the slot portion 76 without pivotally moving'the plate 72. The pin 37 will then move within the slot portion 77 for causing clockwise pivotal movement of said plate 72 about the pin 58 for projecting the bar 70. The

pin 37 will then move into the slot portion: 78.

which, as shown in Fig. 5 of the drawings, is in horizontal position, without causing any movement of the bar 70. Thus as the U-shaped bolt 25 moves from the position shown in Fig. 4 outwardly, to the position shown in Fig. 5, the vertical bolt 16 is projected downwardly for engage-- ment with the keepers 17 and 20, as will be explained hereinafter. Conversely upon moving the U-shaped bolt 25 from the position shown in Fig. 5 to the position shown in Fig. 4, the vertical bolt 16 is retracted to disengage the same from the keepers 17 and 20.

The construction of the vertical bolt or bar 16 and the strut bolt 19 will now be described. As stated above, the bolt 16 comprises the portion 70 slidably projected into the casing. The lower end of said bar 70 is preferably formed with a cylindrical end portion 80 receiving the upper end of a tubular member 31. Attached to the lower end of said tubular member 81 is a bar 83 substantially similar to the bar 70 and aligned therewith, said bar 83 having a cylindrical projection 84 at the upper end thereof received within the lower end of the tubular member and attached thereto by means of a transverse pin 85, or in any other suitable manner. The tubular member 81 is preferably provided with a longitudinal slot 82 and attached to the door 10 is an angle-shaped member 87 having a finger 88 projecting through the slot 82 and into the tubular member 81. A coiled compression spring 88a. housed within the tubular member 81, extends between the finger 88 and the lower end of the cylindrical projection 80. Thus when the bolt 16 which may be made of heavy stock, is projected, the spring 88a will be compressed so that upon retracting said bolt 16, the compressed spring 880. will aid in lifting the bolt 16 so that said bolt as well as the bolts 21 and 25 may be readily actuated by means of the knob or an ordinary key, without the necessity for excessive pressure or strength.

Obviously the casing 14 may have attached thereto or integrally extending therefrom, a suitable projection extending into the tubular member 81 for engagement with the lower end of the spring, to replace the member 87 and its finger 88. The bar 83 preferably extends in the retracted position thereof to substantially the lowor end of the door 10. Attached to the door 10 adjacent the lower edge thereof, is a member 90 having a sleeve portion 91 slidably receiving the lower end of said bar 83 for guiding the same. The keeper 17, which may be of ordinary socket construction and may be attached to the floor in any suitable manner, is preferably of square cross-sectional shape for receiving the lower end of the bar 83 upon projecting said bolt 16.

Slidably mounted on said bar 83 is a yoke member 94 having two parallel wall portions 95 and 96 extending on opposite sides of the bar 83 and an interconnecting wall portion 97 contacting the surface of said bar 83 adjacent the door 10. The walls 95 and 96 preferably extend beyond the bar 83, as shown in Fig. 2 of the drawings. Said walls 95, 96 and 97 are formed with a slot 99 having semi-cylindrical end portions 100, for the purpose hereinafter appearing. A pair of set screws 102 screwed to the wall portion 97, serve to attach the member 94 to the bar 83 in any desired adjusted position. The strut bar 19 comprises an elongated rod 105 having a thickened portionv 106 forming a surface 107 disposed at an acute angle to the longitudinal axis of said rod 105, for the purpose hereinafter appearing. Said. thickened: portion;

106 is further .formed with. a pair: of oppositely extending, cylindrical, portions 108 received Within the slot991andengaged within: the semicylindrical portionsllofiiof .saidslot.. The thickened portion 106 isfurthermore rounded as at shown in Fig. tion thereof; shown in said figure. Thus in the dot-dashv position. shown in Fig; 2,

the outer. end of: the rod is receivedwithini the socketed keeper 20, upon proje'ctingthe bolt 16. Means is provided for retainingthebolt 19 in lifted positionagainstthe bolt 16. To this end, said rod 105'. is provided with a pair of oppositely extending aligned pins 111. Slidably mounted: on said rod 105 is: a U.shaped member 1131having side wall portions 114formed with aligned vertical slots 115 receiving saidpin portions 111 therethrough. The walls. 114 are further formedwith hooked ends llfiyadapted to engage within notches 117 formed in the side wall portions 95 and 96 of the memshown in fully lines .in Fig.2 of'the drawings.-

To this end, theiend. wall 31 of the casing 14 adjacent theedgeoflthe door is provided at the rear edge thereof with a pair of symmetrically disposed notches or grooves 120. Attached to the door 10 is a plate 121 having an opening 122 therein overlying the hole 123 in the door which receives the key cylinder. Said plate 121 is further formed with two spaced, symmetrically disposed projections, 124, the outer edges 125 of which are aligned. Said projections 124 are adapted to be received within the grooves of the casing 14. The entire plate 121 is adapted to be received within the ledge 14a formed in the rear open end of the casing. The ledge is thus preferably formed deeper than the thickness of the rear cover plate 32 to leave the additional space necessary for the reception of the location plate 121. Once the plate 121 is attached to the door with the outer edges 125 of the projections 124 fiush with the outer edge of said door, the casing 14 may be accurately placed on the door so as to properly position said lock for actuation by a key.

It will now be understood that our improved lock may be used with a right hand door or a left hand door. To reverse the lock it is merely necessary to interchange the pivot plates 59 and '72 and to also interchange the bolts 25 and 16. It is for this purpose that the horizontal bolt 21 is formed with two rack portions 38. When used in one position, one of the racks 38 meshes with the pinion 53 and when the lock is reversed the"'other rack38 meshes withthe pinion '53. Obviously the lock may be readily disassembled to reverse the'bolts. The rear cover plate may be readily removed and the pivoting plates 59 -and72 are readily disengagedfrom the cover plate and from'the horizontal and vertical bolts. Furthermore, the U-shaped bolt 25' as well as the bar' 'm' m'ay be easily slidably moved out of the slotsor openings 46 and 47 upon disengaging the pivot plates 59 and 72. The lengthof the vertical bolt lfimay be adjusted by cutting off a portion'of 'tu'be 81. Obviously the strut bolt 19 as well: as the yoke 94 may be omittedif desired.

It will thusbe-seen' that there is provided a device in which the several objects of this inventionareachieved, andwhi'ch is-well adapted to meet the conditions of practical'u'se.

As various possible embodiments might be made of the above'invention, and as various changes might be made in'the embodiment set forth, it is to be understood that all matter hereihisetforth, or: shown 'in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense. 1
